Synchronisation of PDOs via sync telegram

( 310)

9.11.1 Behaviour of the status signal bSyncInsideWindow

C01123 serves to set a time slot for monitoring the synchronisation signal. If the synchronisation

signal received via the bus is in this time slot (around the expected

time of the synchronisation

signal), the bSyncInsideWindow output is set to TRUE.

Up to and including software version V6.0 the following applies:

Due to an error in the implementation, the phase position set in C01122

is included in the

calculation of the time slot. The time slot effective for monitoring around the expected

time of the

synchronisation signal is thus increased by the amount of the set phase position.

Example:

• Sync phase position (C01122

) = 400 μs

•Sync tolerance (C01123

) = 20 μs

 The time slot for monitoring has a size of 420 μs!

The following applies from software version V7.0 onwards:

The faulty inclusion of the phase position set in C01122

into the calculation of the time slot has

been removed. The time slot for monitoring the synchronisation signal only corresponds to the sync

tolerance set in C01123

.

Example:

• Sync phase position (C01122

) = 400 μs

•Sync tolerance (C01123

) = 20 μs

 The time slot for monitoring has a size of 20 μs!

Feedbacks and their remedies

If the bSyncInsideWindow status signal is used in existing systems, this remedy reduces the

monitoring window by the amount of the phase position if it is non-zero. This may cause an

unwanted activation of the monitoring of the synchronisation signal programmed by the user.

Remedy:

When the syn tolerance is increased (C01123) by the amount of the phase position set in

C01122

, the compatible state is restored.
